b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

f9132cebdc Wrap array accesses in macros, which also happen to be lvalues:
ifnet_addrs[i - 1]  -> ifaddr_byindex(i)
        ifindex2ifnet[i]    -> ifnet_byindex(i)

This is intended to ease the conversion to SMPng.

47e83d86d1 Make this compile when there is no pci bus in your kernel.
Note: This should be multiple files, but since it is also broken in
stable, I thought I'd do a fix that could be MFC'd.

This is a MFC candidate.

fa081a357e In order for the MA301 to pass interrupts from the PCCard, you must
go into the PLX 9052's interrupt control register and turn on the magic
interrupt enable bit.

Partial thanks are due to OpenBSD for pointing out that the chip is a
PLX 9052 and pointing me to the datasheet PDF.

84031c85e5 Add support for the Netgear MA301 PCI adapter for the MA401.
It appears that a number of PrismII card vendors seem to be doing the
same thing (that is, using the same PCI bridge chip) to support PCI,
but each with their own vendor/product ID. So rather than cut-n-paste
another if statement into the probe routine, it's probably better to
provide support for a table. Adding new devices will be a lot easier
that way.

419d8080a4 Currently, each wireless networking driver has it's own control program
despite the fact that most people want to set exactly the same settings
regardless of which card they have.  It has been repeatidly suggested
that this configuration should be done via ifconfig.  This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers.  It also provides partial, untested support for the
awi driver.

a LinkSys card here in the office where reading the station address
fails the first time, but works find afterwards. Without this, the
probe fails. I don't think this will negatively impact any existing
cards, but I want to confirm this before MFC'ing.

	Copy wi_{dst,src}_addr from struct wi_frame into faked-up ether_header
	instead of addr1 and addr2. THis means that tcpdump -e will show the

	the BSSID.

	In the future there should be 802.11 support for bpf/libpcap/tcpdump,
	but that is aways down the road.

9ed346bab0 Change and clean the mutex lock interface.
mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

08812b3925 Implement MTX_RECURSE flag for mtx_init().
All calls to mtx_init() for mutexes that recurse must now include
the MTX_RECURSE bit in the flag argument variable. This change is in
preparation for an upcoming (further) mutex API cleanup.
The witness code will call panic() if a lock is found to recurse but
the MTX_RECURSE bit was not set during the lock's initialization.

The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to
MTX_RECURSED, which is more appropriate given its meaning.

The following locks have been made "recursive," thus far:
eventhandler, Giant, callout, sched_lock, possibly some others declared
in the architecture-specific code, all of the network card driver locks
in pci/, as well as some other locks in dev/ stuff that I've found to
be recursive.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out

Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing

dda0e6f54e Update the WaveLAN/IEEE driver:
- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
  the initial work here. One thing I changed was to have the attach
  and detach routines work like the PCI drivers, which means that in
  theory you should be able to load and unload the driver like the PCI
  NIC drivers, however the pccard support for this hasn't settled down
  yet so it doesn't quite work. Once the pccard work is done, I'll have
  to revisit this.

- Add device wi0 to PCCARD. If we're lucky, people should be able to
  install via their WaveLAN cards now.

- Add support for signal strength caching. The wicontrol utility has
  also been updated to allow zeroing and displaying the signal strength
  cache.

- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
  Currently this module is only built for the i386 platform, though once
  the pccard stuff is done it should be able to work on the alpha too.
  (Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
  cards into an alpha with an ISA slot, but we'll see how that turns out.

- Update LINT to use only device wi0. There is no true ISA version of
  the WaveLAN/IEEE so we'll never use an ISA attachment.

- Update files.i386 so that if_wi is dependent on card.
